.Application filed March 25, 1901, Serial No. 52,809.

To all 'wwm 'it mayyconcern:

Be it known that I, RoBERrI-I. RIDDLE, a citizen of the United States,residing at Dayton, in the county of -Montgomery and State of Ohio, haveinvented certain new and Useful Improvements in Cash-Registers, of whichI declare the following to be a full, clear, and exact description.

This invention relates to improvements in cash registers and has morearticular relation to improvements in key ocking devices for the same.

The object of the invention is to providel means for compelling acertain sequence of operation of the keys of a cash'register.

The accompanying drawing forming part of this specification represents avertical section through a machine well known in the art and to-which asshowing one application of my invention I have attached -myirnprovement.

In the drawing 1 represents thel frame of the machine, 2 andB the keysand 4 'my improved lock or detent.

In the present instance I have shown my invention as appliedV to avseries of keys arranged in a single bank but it will be at onceapparent that a series of such plates might be provided, one for eachbank and connected together so as to have the different banksinterlocking in the same manner as will now be described forI thesinglewli'vided bank shown.

In the type of machine shown which is old and well known in the art itis the prac# tice to divide the keys in one of the banks into two groupssuch for instance as a group representing clerks or department keys anda group representing special transactions. When such a division of abank is made means are provided whereby a key in each group may bedepressed and latched in its depressed position but this depressionshould be according to' a predetermined sequence. The sequence in thepresent instance is first one of the three lower `special transactionkeys and then one or' the six upper clerks keys 2. To compel thissequence of o eration I provide the aforesaid segmenta detent 4. Thisdetent is slidably mounted on the frame 1 by means of headed screws 5which pass through elongated slots6 formed in said detent. pins 7 arearranged to pass into bayonet slots 9 formed in the detent while thepins Specification of Letters Patent.

8 are arranged to coperate with diagonal slots also formed in thedetent.

It will be seen from the above and by ref 'erence to the drawings thatshould one of vthe' keys 2 be operated before one of the keys 3 thedetent 4 will be forced upward, and thus move the slots 9 out ofalinement with the pins 7 and prevent operation of any of the keys 3.Should a key 3 be first operated, however, its pin 7 will pass to thebottom of its slot 9 without moving the detent and the latter may besubsequently moved by the operation of one of-the keys 2; the lowerlpart of the bayonet slot receiving the pin 7 during such operation, andobviously holding the key in its depressed to its normal` position, otcourse, forces the deteut 4,- baek to its normal position also ready forthe nekt operation.

, Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

l. In a cash register, the combination with a series of keysl dividedinto a'plurality of rroups and all normally free to be operated, ofmeans cooperating with said keys for compelling a certain sequence ofoperation, said means permitting the simultaneous retention of a key ineach group in depressed position when the proper se- 2. In a cashregister, the combination with a series of stop keys for setting theregister for proper operation divided into a plurality of groups and allnormally free to be' operated, of a movable locking member operated byany key in one of said groups and when so operated loking all the keysof the remaining group.

3. In a cash register, the combination with a series of keys arrangedina plurality of groups, of a locking member for said keys moved by onlyone of said groups and adapted when so moved. to lock in depressedposition thekeys of the other group.

4. In a cash register, the combination with a series of keys arranged ina plurality The return ot' one of the keys 2A of groups, of a detentformed with :incline slots, the walls of which are adapbted to bewith aseriesv of keys arranged in groups and each provided with a laterallyprojecting pin, of ajdetent having incline slots which the pins of onegroup enter and angular slots which the pins of the remaining groupenter.

6. ln a-cash register, the combination with a series oic keys dividedinto a plurality of groups and all normally free to be operated, of amovable locking member operated by any key in one of said groups and notaffected in its operation by the depression of the keys in `the othergroup, and when operated adapted to lof-k the keys of the latter group.

T. In a ezish register, the Combination with a series or". keys dividedinto a plurality of groups, oi a detent for said keys cooperating withboth groups of keys but arranged to be inoved by one. group only andwhen so n'ioved adapted to lock the keys of the other group but notall'eeted in its operation by ,the depression of the keys of the lattergroup. Y 8. In a cash register the combination of a series of keysdividedinto a plurality of `groups, of a sliding detent cooperating Withboth groups of keys but arranged tobe moved by one group only so as tolook the keys of the remaining group.
